Employment spectrum of IDDM

Occupational issues in 158 insulin-dependent diabetes mellitus (IDDM) individuals and 158 matched nondiabetic siblings were examined in a case-control design to evaluate the role of diabetes in the employability of people with IDDM. Overall, the IDDM cases were more likely to report refusal for a job at some point in their lives (56 vs. 42%, P = .02) than were the nondiabetic control siblings. Surprisingly, individuals who told job interviewers about their diabetes were more likely to report job refusal than their siblings (64 vs. 42%, P = .005), whereas individuals who did not mention their diabetes reported rates of refusal similar to their siblings (44 vs. 41%). IDDM cases were also less likely to be employed full time compared with siblings (55 vs. 73%, P = .001). Reduced employment in IDDM respondents was related to work disability. Reported work disability was more than seven times greater in the IDDM than the sibling group. The presence of diabetic complications was the primary factor related to work disability. Although 13% of IDDM respondents were unable to work because of disability, absenteeism among IDDM cases currently working did not differ from that of the nondiabetic siblings. Diabetes was not significantly associated with career levels or household income levels reported by the IDDM group. Disability, however, had a strong detrimental influence on these variables. The results suggest that hiring practices by employers may still be discriminatory toward individuals with IDDM. Once hired, the employment experiences of the IDDM population appear to be similar to the experiences of the nondiabetic population, provided the development of disabling diabetic complications has not taken place.
